2N6079

Overview

The Microchip Technology 2N6079 is a silicon-controlled rectifier (SCR) designed for high-power switching applications. It features a TO-220AB package and supports a repetitive peak forward blocking voltage of 400 V with a gate trigger current of 100 mA. The device handles an on-state RMS current of 35 A and can withstand a non-repetitive peak surge current of 350 A. Operating within a junction temperature range of -40°C to +125°C, it provides robust performance in industrial environments.

Feature Summary

• High power handling capability with 35 A on-state RMS current rating
• Robust surge tolerance supporting 350 A non-repetitive peak currents
• Integrated thermal protection mechanisms for reliable operation
• Standardized TO-220AB mounting style for efficient heat dissipation

Applications

• AC power regulation circuits utilizing phase control techniques
• Solid-state relay implementations for heavy loads
• Battery charging equipment managing high current inputs

Procurement Notes

Verify the specific suffix codes against official Microchip documentation to ensure correct pinout and thermal characteristics. Confirm RoHS compliance status as military variants may differ. Check lead times due to potential supply constraints for standard discrete semiconductors. Validate package integrity upon receipt to prevent mounting failures.

Selection Notes

Select this component when applications demand high current capacity exceeding standard transistor limits. Ensure the circuit design accommodates the required gate trigger current of 100 mA. Verify that the PCB layout supports the TO-220AB package dimensions and thermal requirements. Consider derating factors for ambient temperatures approaching the maximum junction limit.

Part Context

This SCR belongs to the broader family of power semiconductor switches manufactured by Microchip Technology. It complements other thyristor devices used in similar high-power domains. The component serves as a fundamental building block for converting AC power into controlled DC outputs or regulating AC loads directly.

Replacement Considerations

Consult official cross-reference guides for equivalent SCRs with matching current and voltage ratings. Verify pin compatibility before substituting with devices from other manufacturers. Ensure thermal resistance values are comparable to maintain system reliability.
